Fusion, graphs and $ \mathrm{Out}(F_n) $.
We will attempt to introduce fusion systems in a way comprehensible to a Geometric Group Theorist. We will show how Bass–Serre thoery allows us to realise fusion systems inside infinite groups. If time allows we will discuss a link between the above and $ \mathrm{Out}(F_n) $.
